None of the other four peptides examined (bombesin, galanin, neurotensin and vasoactive intestinal peptide) differed significantly between the two groups.

Total basal concentrations of neurotensin and somatostatin were higher in GD than in controls and NP, and no change was found after the glucose load or mixed meal in GD.

Among these, melanin-concentrating hormone (MCH) and neuropeptide Y (NPY) are potent appetite stimulants, whereas alpha-melanocyte-stimulating hormone (alpha-MSH), neurotensin, and glucagon-like peptide (GLP)-1(7-36) amide have appetite-suppressing properties.

In the current study, we describe the functional interactions between orexigenic (appetite-stimulating: MCH and NPY) and anorectic (appetite-suppressing: alpha-MSH, neurotensin, and GLP-1) peptides after intracerebroventricular (i.c.v.) administration in the rat.
|
79 |
9792536
|
The i.c.v. administration of GLP-1 completely prevents the orexigenic effects of both MCH and NPY.
|
80 |
9792536
|
However, i.c.v. administration of alpha-MSH prevents only the orexigenic effect of MCH, as we have previously shown, but does not prevent the effect of NPY on food intake.

Thymic epithelium, including nurse cells (TEC/TNC), as well as other thymic stromal cells (macrophages and dentritic cells), express a repertoire of polypeptide belonging to various neuroendocrine protein families (such as the neurophypophysial, tachykinin, neurotensin and insulin families).
|
93 |
9876242
|
Oxytocin (OT) is more expressed in the TEC/TNC than vasopressin (VP); insulin-like growth factor 2 (IGF-2) thymic expression predominates over IGF-1, and much more over (pro)insulin.
|
94 |
9876242
|
Thus, OT was proposed to be the self antigen of the neurohypophysial family, and IGF-2 the self antigen precursor of the insulin family.
|
95 |
9876242
|
Using an animal model of autoimmune type 1 diabetes (BB rat), we have shown a defect in intrathymic expression of the self antigen of the insulin family (IGF-2) and in IGF-2-mediated T-cell education to recognize and tolerate the insulin family.

Neuropeptide Y (NPY), melanin concentrating hormone (MCH), orexins A and B, galanin, and agouti -related peptide (AgRP) all act to stimulate feeding while alpha-melanocyte stimulating hormone (alphaMSH), corticotropin releasing hormone (CRH), cholecystokinin (CCK), cocaine and amphetamine regulated transcript (CART), neurotensin, glucagon-like peptide 1 (GLP 1), and bombesin have anorectic actions.(1) Leptin, expressed in the periphery in white adipose tissue, acts in the CNS to modulate the expression of several of these hypothalamic peptides.(1) This creates a functional link between the adipose tissue and the brain that translates the information on body fat provided by leptin to input into energy balance regulating processes.

In the current review we examine the significant role of the melanocortin system (alphaMSH, agouti and AgRP peptides, and their receptors and mahogany protein) and melanin concentrating hormone in the regulation of energy balance.

When energy stores are low, production of leptin from adipose tissue, and thus circulating leptin concentrations fall, leading to increased production of hypothalamic neurotransmitters that strongly increase food intake, such as neuropeptide Y (NPY), galanin and agouti-related protein (AGRP) and decreased levels of alpha-melanocyte-stimulating hormone (alpha-MSH), cocaine and amphetamine-regulated transcript (CART) and neurotensin that reduce food intake and increase energy expenditure.

We show here that long transcribed but untranslated CGG-repeat tracts are toxic to human cells and alter the expression of a wide variety of different genes including caspase-8, CYFIP, Neurotensin and UBE3A.

Divergent regulation of proopiomelanocortin neurons by leptin in the nucleus of the solitary tract and in the arcuate hypothalamic nucleus.
|
122 |
16505217
|
Proopiomelanocortin (POMC) neurons in the arcuate nucleus (ARC) of the hypothalamus are activated by leptin and mediate part of leptin's central actions to influence energy balance.
|
123 |
16505217
|
However, little is known about potential leptin signaling in POMC neurons located in the nucleus of the solitary tract (NTS), the only other known population of POMC neurons.
|
124 |
16505217
|
The contribution of NTS POMC neurons versus ARC POMC neurons in leptin action is thus undetermined.
|
125 |
16505217
|
We show here that in contrast to POMC neurons in the ARC, leptin does not stimulate phosphorylation of signal-transducer and activator of transcription 3 in NTS POMC neurons of POMC-EGFP reporter mice.
|
126 |
16505217
|
In addition, leptin does not induce c-Fos expression in NTS POMC neurons unlike ARC POMC neurons.
|
127 |
16505217
|
Fasting induces a fall in POMC mRNA in both the ARC and the NTS, but different from the ARC, the reduction in NTS POMC mRNA is not reversed by leptin.
|
128 |
16505217
|
We conclude that POMC neurons in the NTS do not respond to leptin unlike ARC POMC neurons.
|
129 |
16505217
|
POMC neurons in the hypothalamus may therefore mediate all of leptin's signaling via POMC-derived peptides in the central nervous system.

Some self-antigens (oxytocin, neurotensin, insulin-like growth factor 2 [IGF-2]) have been selected to be predominantly expressed in thymic epithelium and to be presented to thymus T cells for educating them to tolerate other antigens related to them.
|
163 |
17192574
|
In the insulin family, IGF2 is dominantly transcribed in cortical (c) and medullary (m) thymic epithelial cells (TECs), whereas the insulin gene (INS) is expressed at low level by only a few subsets of mTECs.
|
164 |
17192574
|
Intrathymic transcription of both IGF2 and INS is under the control of the autoimmune regulator (Aire) gene.
|
165 |
17192574
|
The highest concentrations of IGF-2 in the thymus explain why this peptide is much more tolerated than insulin, and why tolerance to IGF-2 is so difficult to break by active immunization.
|
166 |
17192574
|
The high level of tolerance to IGF-2 is correlated to the development of a tolerogenic/regulatory profile when the sequence B11-25 of IGF-2 (homologous to the autoantigen insulin B9-23) is presented to DQ8+ type 1 diabetic patients.
|
167 |
17192574
|
Since subcutaneous and oral insulin does not exert any tolerogenic properties, IGF-2 and other thymus self-antigens related to type 1 diabetes (T1D) should be preferred to insulin for the design of novel specific antigen-based preventive approaches against T1D.

Recently, we identified a novel crosstalk between insulin and G protein-coupled receptor (GPCR) signaling pathways in human pancreatic cancer cells.
|
169 |
19679549
|
Insulin enhanced GPCR signaling through a rapamycin-sensitive mTOR-dependent pathway.
|
170 |
19679549
|
Here, we determined whether metformin disrupts the crosstalk between insulin receptor and GPCR signaling in pancreatic cancer cells.
|
171 |
19679549
|
Treatment of human pancreatic cancer cells (PANC-1, MIAPaCa-2, and BxPC-3) with insulin (10 ng/mL) for 5 minutes markedly enhanced the increase in intracellular [Ca(2+)] induced by GPCR agonists (e.g., neurotensin, bradykinin, and angiotensin II).
|
172 |
19679549
|
Metformin pretreatment completely abrogated insulin-induced potentiation of Ca(2+) signaling but did not interfere with the effect of GPCR agonists alone.
|
173 |
19679549
|
Insulin also enhanced GPCR agonist-induced growth, measured by DNA synthesis, and the number of cells cultured in adherent or nonadherent conditions.
|
174 |
19679549
|
Low doses of metformin (0.1-0.5 mmol/L) blocked the stimulation of DNA synthesis, and the anchorage-dependent and anchorage-independent growth induced by insulin and GPCR agonists.

Leptin action via neurotensin neurons controls orexin, the mesolimbic dopamine system and energy balance.
|
178 |

Thus, LHA LepRb(Nts) neurons mediate physiologic leptin action on OX neurons and the mesolimbic DA system, and contribute importantly to the control of energy balance.

Quantitative PCR and liquid chromatography-mass spectrometry proteomic analyses of isolated, FACS-purified CCK-eGFP-positive cells demonstrated expression of not only CCK but also glucagon-like peptide 1 (GLP-1), gastric inhibitory peptide (GIP), peptide YY (PYY), neurotensin, and secretin, but not somatostatin.
|
185 |
23064014
|
The coexpression pattern was further confirmed through a cell ablation study based on expression of the human diphtheria toxin receptor under the control of the proglucagon promoter, in which activation of the receptor resulted in a marked reduction not only in GLP-1 cells, but also PYY, neurotensin, GIP, CCK, and secretin cells, whereas somatostatin cells were spared.
